Muhammad Ali and Jonah Lomu. Both had a combination of speed, endurance, size, coordination, strength, agility... near enough everything you could ever need. These two could have very good at the widest variety of sports imo.

Agree. One of the most graceful athletes of all time. The hand, eye coordination was off the charts. Not to mention his damn stamina. Bouncing up and down like that, at that size is extremely taxing.
